There’s a great shortcut for those of you with Windows 7 and Vista laptops. Press the Windows Key + X and you’ll get a dashboard that lets you monitor and control key functions on your laptop.
Here’s what it looks like.
You can adjust brightness and sound with slider bars.
Check the status of your battery…
and turn wireless on or off and monitor your connection.
You can also connect to an external display and control that display, plus sync your settings all from one handy control panel.
Pressing Win + X in Windows 8.1 will bring up a version of the Start Menu, which includes the option of going to the Mobility Center.
It looks pretty much the same as it does in 7, but you do have an option for Presentation Settings.
If you have a Windows 7 laptop, give this shortcut a try.
